HELP Please what`s going on with this CARTRIDGE

A bit of woofer excursion is normal on vinyl. Too much is not necessarily good or normal. Generally, too much can mean improper tracking. The other possibility is the output of the cartridge. Which cartridge? What is the output? Is the record you are playing warped? What is the rest of your equipment?

If you want to call me or me to call you, I would be happy to help. Email me your number and I can call anytime.

It's the compliance of your cartridge and the mass of the tonearm that it is mounted to that is causing your problem.
It seems like a not so perfect match. here is a link for futher review:

Your description suggests that there is a resonance problem between the tonearm and the new cartridge. If the resonance point of the cartridge/tonearm combination, which is a function of the tonearm's mass and the cartridge's compliance, is too high (typically in the 11-12 Hz range), then the tonearm can begin vibrating (similar to oscillation) so severely that the tonearm / cartridge can actually bounce clear of the groove. If you have a test LP with a resonance mode band, you should use it to check if your tonearm / cartridge combo to determine if it has a pronounced resonanance mode. If so, you will probably have to get a different cartridge (one with either higher or lower compliance) that works with your tonearm.

I had the same problem on my Linn with a Grado , and switched to a Shure V15VXMR and all is well but consult your tonearm manufacturer to find out what type of cartridge works best.

Some tests that you too can conduct at home. Make sure that the wife and kids are out of the room first. "Nothing to see here, keep moving". First, with the table off, lower they stylus onto a record. Again, the turntable should not be spinning. Raise the volume on the preamp to just above loud listening level. You may want to gently tap the stand, not the plinth, but this may not even be necessary. If howling starts, immediately reduce the volume. Congrats, you have acoustic feedback. Second test, put on a warped record, view the arm from the side as it tracks the warp. Does the arm go up and down as it tracks the warp or does the cantalever deflect? If the cantalever deflects, congrats you have an arm that is too massive for the cartridge compliance or a worn cartridge suspension (the latter is unlikely given the new cartridge). The big guess: you have vented (acoustic suspension) speakers, no? Done with tests to determine problems. Now tests to determine solutions. First, find three tall empty water glasses, identical will work best here. Put them upside down supporting the turntable. Yes, under the turntable. If this helps it is certainly #1 above. You will need a wall shelf, such as the Target or Rega, or you will need to move your rack where it is not in an area excited by bass nodes, or you will need a suspension like vibraplane, or you will need to invest in Anchor Hocking. The second problem is a bit more problematic. You could really help all of us by naming names and telling us what cartridge and turntable you are using. It would cut out a lot of the guesswork but hey, you must think that this is fun. Tell me, are you one of those guys that goes to the doctor and says, "Hey Doc, guess where I hurt?". Thought so. But seriously, if you have a universal headshell, we may be able to find one less massive or a similar fix some arms, like the Audioquest will allow us to use fluid damping which can really help. Gotta know before we can go though. Ain't this a great hobby. Just think, you could've been breeding race horses or growing orchids. Just not in the same pasture.
